To all whom t may concern:

Be it known that I, MIGUEL LLODRA, a resident of Manila, Philippine Islands,',have

y invented certain new and useful Improvements in Distilling pp'aratus, of,which. the following is a specification. 1

My invention is an improvement'indis-4 tillingr apparatus and consists in certain novel constructions and combinations of hereinafter described and claimed.

Referring to the drawings forming a part hereof Figure 1 is a diagrammatic view of v the furnace and the caldrons.

my distilling apparatus. Fig. 2 is a vertical section through the distilling column. Fig. 3 is a vertical longitudinal section through Fig. 4 is a section onv the line 1r-4 of Fig. 5. Fig. 5 is a section on the line 5-5 0f Fig. 3. Fig. '6

` is a vertical section through one of the sections of the' distilling column. Fig. 7 is a plan view of same. `Fig. 8 is a perspective view of the partition between the caldrons, and Fig. 9 is avertical section through the condensing cylinder.

In the practical application of my invenL tion, I provide a furnace A, comprising a fire box -B arrangedl at one end and extending to approximately the longitudinal center p. thereof. and at the rear of the furnace are llues b2 b3, which double forward alongside the lire boxto a point adjacent to the front thereof, and again double back upon themselves as at b4 b5 to the rear of the furnace where they are united to form a single passage b which winds spirally upward within the wall of the rear portion of the furnace as at t7, tothe chimney. The'fire box is provided with grate bars bs, dividing it into the re box proper andthe ash'chamber.

' A caldron C is arranged above the re box and above the flue portions b2 b3 b4 b5, andV at the rear thereof is a second caldron com* prising an upper portion D and a lower portion E separated from each other by a partition wall d, the second caldron being arl Vranged within lthe Winding of the spiral portion of the flue. The partition d comprises a substantially horizontal .portion d and an I caldron E and the upper caldron D.

parts The caldron C is provided with a pipe c 5 leading from the bell c thereof, upwardly, horizontally, and downwardly into the lower caldron E, and the pipe c2 having a valve cX forms a communication between the caldron E and the caldron C adjacent the bases thereof. vArranged in the sides of the caldrons D and E are pipes d, d?, communicating with the vertical pipe e', which in turn communicates with the horizontal pipe c2, the pipes d6, d?, being provided with a suitable valve eX, whereby to control the flow of liquid through the pipes. ne, Arranged above the caldron D is a distilling column F composed of a series of sections f, each comprising the outer casing f', having arranged therein the partition 7"2 provided with a central openingfa, the edges of the opening being flanged as at f4, and Vsupported above the opening, is an inverted basin-shaped hoodj'5 having secured at equidistant pointson the circumference thereof `the legsf, the lower end of the legs being se-` cured to the partition by boltsj'7. The hood f5 is provided with a centrally arranged aperture fs for a purpose to be hereinafter de` scribed, and each of the sectionsis provided with a pipe f extending above and below the partition and'forming a means of communication between the respective,sections. The lower section of the distilling column dill'ers in some respects from thc remaining sec-tions, in that it is provided with two pipes f, the lower ends of the pipes extending into Athe caldron I), and arranged below the open ends of the latter pipes are receptacles G for a purpose to be hereafter described.

The distilling column. is provided with a bell-shaped cover f1, having a central aperture f, communicating with a pipe 12, forming a communication between the distilling column and the worm of the condensing cylinder H.

The condensing cylinder H is arranged adjacent the distilling column, and comprises an outer casing h having arranged therein the spiral Worm h", communicating at one end as before stated with the pipe f 2, and at the other end with the pipe if communicating with the spiral worm i 1n an auxiliary refrigerating tank I, the lower end of .the said' worm communicating in turn by means of the pipe t with a third spiral worm k having a discharge pipe lc5 and supported ina refrig- IOO erating column K. The worm h also comlmunicates with the pi e t" leading from the wormt to the worm k, y means of the valved pipe 7f3, the valve being provided in order that the pipe k3 may be closed when it is desired to make use of the auxiliary refrigerating tank I.

Areceiving tank M is arranged above and adjacent to the refrigerating column'K and communicates therewith by means of a pipe m. The refrigerating column K communicates with the condensing cylinder H by means of a pipe h2, and the condensing cylinder communicates by means-of the pipe h3 -With the second section of'the distilling colwith by means of a pipe When the prode ucts of distillation are to be passed through the auxiliary refrigerating tank the valve in the pipe k3 is closed thus constraining the said products to pass through the Worm i in the said tank I. i

In operation the wash is pumped into the receiving tank, iowing from thence to the refrigerating column K, completely filling the same and surrounding the worm therein.

From the refrigerating column the wash passes upwardly to the condensing cylinder H surrounding the worm therein, and thence to the second section of the distilling column F. The wash is introduced at-the second section, since did it enter the lower sectionit could not iow readily, because of the ebullition of the alcohol vapor rising from vthe caldron D immediately below. As the section is filled the. wash rises to the level'oi the mouth of the communicating tubes and passes downward into the lower section where the process is repeated, and the wash passes through the second series of tubes into the receptacles H, which are for the purpose of preventing the retardation ofthe flow by the action of the vapor rising from the caldron. Overllowing the receptacle, wine begins to fill the caldron D the liquid resting' upon the partition d. The wine is drawn oil from the caldron D by means of pipes d, Z7 into the lower caldron E, and thence through the lower pipe c2 to the caldron C. Here the wash receives the strongest heat being directly over the fire box, and a considerable quantity of the wash is converted into vapor passing upward and downward through the pipe c into the caldron E, whence it passes upward through the liquid therein to the pipe d* and by its lateral branches intol the caldron D. F rom the caldron D the vapor passes upwardly through the distilling eolumn wliich 1s ordinarily composed of approximately twenty sections, the vapor heing permitted to pass from section to section by means of the apertures in the partition and in the hood. From the. distillingl column the vapor passes through the spiral worin in the condensingcylinder where a part of it is condensed and is drawn oli through the pipes 7L, h5, h. and returned into the distilling column. The vapor of the high proof alcohol passes from the condensing cylinder to the refrigerating column, where the processmf condensation is completed. In making high grade alcohol the vapor is passed from the condensing cylinder to the auxiliaryv refrigeratiiig tank, in which the worin is surrounded by cool water instead of by the wash.

It will be evident from the description, that the wash as it passes through the rerigerating column and the condensing c vlinder, willcondeiise the vapor from the distil ling column, and that the vapor will give up its heat to the incoming wash, thus gradually heating the same during its passage toward the caldron.

The caldron C, is provided with a valvcd 'discharge pipe c shown in Fig. 3; it is used in testing in the following manner. Toward the end of the distillation, the valve in the pipe c4 is'opened and a light is applied to the vapor which issues therefrom, which vapor igiiites if it contains alcohol. The process is continued until iio alcohol is found in the vapor.

A brace LX extendshetween the pipe 7i and the condensing cylinder.
